In Natty:   I can confirm that it still just says Drag and Drop
threshold without any explanation.  Yes, it's still an issue, because I

 That's also exactly how I'd describe the idea of allowing all users to set
 timezone without authentication on laptops. :-p

Well, then the easy answer is to do neither.

 Anyway, it's not the place to discuss the choice of automated timezone
 detection: go to the gnome-control-center list if you really to want to
 argue this.

No thanks.   People love to add features.   You can't stop someone who 
has a pet idea that they haven't
thought through very carefully.They just produce self-justifying 
reasons and don't listen.

Me, I'll just turn it off when it appears.Then in 5 years, either it 
will become useful,
or the distros will cause it to default to off.

Re: [Bug 696115] Re: Timezone should not require superuser on laptop

2011-01-04 Thread gpk
Actually, on consideration, I don't think that automatic detection of 
the timezone
is a viable solution.It suffers from all kinds of potential problems 
like
What does it do if it's connected to a VPN?.  If I connect via VPN 
to my
office in the UK when I'm in France, I'd get the incorrect time.

Or, if I'm in the airport and I'm not yet connected to a network in my 
new location,
it will be silently giving me incorrect timezone information.   It'll be 
telling me
what time it is in the other country.That's acceptable if you know 
you have to
set it manually, but people will depend on an automatic system, and miss 
their
connecting flights.

The trouble this will cause is a classic computer problem:  it will be a 
system that is
smart enough to be right most of the time.Being mostly right, people 
trust it
and depend on it, and then get surprised in those cases where it is wrong.

Besides, there is a laptop-detect package in Ubuntu:

 $ aptitude show laptop-detect
 Package: laptop-detect
 State: installed
 Automatically installed: no
 Version: 0.13.7ubuntu2
 Priority: optional
 Section: utils
 Maintainer: Ubuntu Core Developers ubuntu-devel-disc...@lists.ubuntu.com
 Uncompressed Size: 57.3k
 Depends: dmidecode ( 2.8-2)
 Description: attempt to detect a laptop
  laptop-detect attempts to determine whether it is being run on a 
 laptop or a
  desktop and appraises its caller of this.

So, it is certainly technically possible to tell if you're on a 
laptop.Therefore gnome can make
decisions based on that fact.

 I think the whole point will become obsolete anyway when GNOME 3

 People using VPNs are not the majority, and we can disable automated detection
 of timezone if we're connected over a VPN. Plus, we can also use GPS devices
 when present.

OK.   Kind of OK, anyway.  But that means a traveller has to know 
and remember the rule
about VPNs.   If they don't, they will swear at you. You will get 
people saying I know I
connected to the network, why didn't the damn thing set the clock properly?

And, doubtless, developers will respond RTFM. But RTFM is a 
hopeless task these days!
My Ubuntu system has tens of thousands of pages of documentation.  You 
have to design a
system that will not mislead people in important ways, even if they have 
had better things
to do than read the Gnome documentation.

 If people are smart enough to change their timezone manually, they are smart

 because it has no way of finding out you've moved.


Wrong. It's a very different process in the two cases.

Manual case:   you just have to remember did I set it or not?*You* 
are the only actor.

Automatic-but-imperfect case:   You have to understand how the automatic 
time-zone setting logic works.
1) You have to know that it gets its time from looking up its IP address 
in a table.
2) You have to keep track of whether the computer has connected to a 
network.
   2a) It may connect without your knowledge -- if you go somewhere you 
have been before, it
  may detect up a WiFi network where it has the password and 
autoconnect.
   2b) It may fail to connect somewhere you expect a connection.
Hardware could be down,
  or overloaded, or the signal could be too weak, or a password 
expired...
3) Even if it does connect, do you know that it has a global IP address 
in the right country?
 3a) There's the VPN problem.
 3b) There's the possibility that you have a IP address behind a 
firewall.   You may be getting
data, but it might not be able to deduce where it is.
 3c) You may be getting your IP address from a cellullar base 
station on the other side of the border.
4) The software is depending on a map from IP addresses to geographical 
location.
  4a) How accurate is that map?
  4b) How rapidly is it updated if some big ISP moves a block of IP 
addresses from one time zone
to another?

In principle, you need to run through that entire checklist each time 
you've looked at the clock.
That's a different, and harder task from just remembering to set the clock.

Or, to be sure, you can open up the timzeone widget and check to see if 
the computer's idea of the
time zone agrees with reality.   But, if you're going to do *that*, you 
might as well just set it.

Another argument is that from a human social point of view, blaming your 
computer for having
the wrong timezone just doesn't work when you miss an appointment.   
Whoever you
try to apologize to will just be thinking What an idiot!  Everyone else 
can keep track of
what time zone they're in.


Anyhow, it's one of these things that isn't a good idea to automate, 
unless you can do it
really well.



 So you'd suggest computers should always wait for users to do things manually,
 just to avoid being smarter than them? The automated solution is better
 than nothing. Anyway, discussing this here is pointless since it will be
 implemented in GNOME and I'm not involved at all in this work.


No.   I suggest that UNTIL THE AUTOMATED SYSTEM IS 99.999% CORRECT, it
is better to do it manually.The automated solution can be far worse 
than nothing.

Just imagine!You fly into Paris for a job interview.   You glance at 
your laptop
and decide you have time for a espresso.   You don't even think about 
network
connectivity and clocks.  You arrive an hour late for the interview 
because the
darn time zone is wrong.

Are you going to be happy?

Essentially, the trade-off is a minor convenience 99.999% of the time, 
versus a
modest (or major) disaster 0.001% of the time.

Oh, that's silly!

It's a laptop, darn it!The other users will (almost certainly) be on
the console, and they'll be in the same time zone your are in.   (Unless
they have *very* long arms.)

What you are proposing is not the normal use case for a laptop -- you
seem to be thinking that I carry my laptop around so that people can ssh
into it. That's quite rare.

I suggest that laptops are either:
1) single user
* in which case changing the time zone won't hurt other users,
or
2) physically shared amongst several people
* in which case, they are in the same time zone, and if one user sets the 
zone, that is a positive benefit to other users,

Occasionally, they might be 
3) multi-user, shared amongst a small cooperating group of users.In which 
case if someone fools with the time zone, you send them a nasty e-mail.

And they will very rarelyl be used as servers occupied by untrusted
users out to cause trouble.

In use cases 1 and 2, changing time zones is a real benefit.In 3, it
is largely harmless.

at all.Instead, evince exits with status zero each time, indicating
success.

[Bug 669803] [NEW] exit code zero on failure

2010-11-02 Thread gpk
Public bug reported:

Binary package hint: evince

Evince reports success (exit code 0) even when it cannot display a
broken PDF file.

$ evince /usr/lib/R/site-library/Zelig/doc/static/intro.pdf
Error: PDF file is damaged - attempting to reconstruct xref table...
Error: Couldn't find trailer dictionary
Error: Couldn't read xref table
Error: PDF file is damaged - attempting to reconstruct xref table...
Error: Couldn't find trailer dictionary
Error: Couldn't read xref table
desk:~$ echo $?
0
$
Evince gives a big red banner saying - Unable to open document  PDF document 
is damaged but still reports success,
so that code like
for n in *.pdf
do
  evince $n || echo $n
done

does not work as expected.


(Incidentally, that file is part of the r-cran-zelig package -- it appears to 
be truncated.)

[Bug 654391] [NEW] No obvious way for root to cleanly shut down a session

2010-10-04 Thread gpk
Public bug reported:

Binary package hint: gnome-session

There does not seem to be a way for root to cleanly shut down a
particular gnome-session.

Obviously restarting gdm works, but that kills all sessions.  In my 
environment, users
share machines and we have lots of switch user activity. What I'm really 
trying
to do is to automatically clean up those sessions that are left and forgotten:
otherwise they build up and eventually every user is logged onto every machine.

Apparently, you need to send a message on the dbus to gnome-session, but 
getting the session ID
for a particular user/process ID isn't trivial.   One would really like to be 
able to send
a signal to gnome-session, and have it gracefully shut down whatever it can.
(Obviously, I can do kill -9, but that can cause trouble if gnome-session needs 
to do clean-up
activities.)

So, _basically_, the bug is that gnome-session ignores all signals.   It 
shouldn't.   There are perfectly
good reasons for responding to signals.

[Bug 643825] [NEW] Need explanation for Drag and drop threshold

2010-09-20 Thread gpk
Public bug reported:

Binary package hint: gnome-control-center

The Mouse Preferences - General - Drag and Drop - Threshold
needs a bit of explanation.

Is big good?   Is it macho?Is small better?   Generally, what does it do?
You probably know, but I'm not sure and I bet there are millions of
other people who don't know what it does.

Most notably, this is the only option on that window that you can't easily
experiment with.  So, you have no trivial way of finding out what it means, 
either.

This is a minor bug, but a real one, especially for newcomers.

[Bug 232469] Re: wget does not use network proxy in some cases

2009-12-13 Thread gpk
Well, it still doesn't work in karmic, despite all the discussion of
whose problem it is.Flashplugin-nonfree still does this:

Setting up flashplugin-installer (10.0.42.34ubuntu0.9.10.1) ...

Retrying.

And /etc/apt/apt.conf contains this:

Acquire::http::Proxy http://192.168.2.1:8113/;;

Look, suppose the problem is really wget's problem.   OK?   Then why
can't flashplugin-nonfree solve this mess by simply passing a -p flag
to wget?   Then, when (and if) the wget people get off their collective
a***es (Hah, British!) it will continue to work, and the '-p' flag could
eventually be removed.

Not my problem... it's their problem...   sheesh!

There is a well-known idea in designing network protocols: anything you
produce should adhere strictly to the standard, but you should accept
small unambiguous deviations from the standard.   The same should apply
to packages.   They should do the right thing, but not necessarily
depend on other packages being perfect.

 But that is not a solution , since this would probably prevent the
 notification when the disk is really failing.

This is really a statistical problem.   Computer programmers shouldn't
argue. The thing is, it's very much like earthquake prediction.

If you predict an earthquake in San Francisco often enough, eventually
you'll be right.The San Andreas fault is there, and eventually it's
going to let go.The same with everyone's disk drives.However,
it's really not a good idea to warn San Francisco every month when
it might be 50 years until the next big earthquake.

People who predict earthquakes have understood the problem and don't
issue predictions because they know they cannot predict well enough
to be useful.   People who predict disk drives should do the same.
If you read the actual research papers on the subject, they come
to that conclusion.

The trouble is that if you are predicting an event that doesn't happen
very often, you can be in a difficult situation where
(a) You know the event is much more likely than normal, and
(b) the event is still very improbable.

So, for instance with disk drives, the average probability of failure
is about 1 in a thousand per month: 0.1% per month.If you
look at the SMART information, you can sometimes tell that this
disk drive is, perhaps, 5 times more likely to fail than normal.
But that's _still_ _small_.It's still 0.5% per month.

So, even after certain indicators of failure happen, there
might still be less than a 1% chance that the disk drive will
fail soon.In that case, the best thing to do is to
remain silent.

Why?   Because if someone listens to the warning, and acts on it,
the cost will be relatively large. Whereas the probability
of failure is still relatively small.

If you really have your heart tied to this software, if you really
love it like your first child, and you really don't want it disabled,
then the thing to do is to minimize the damage it causes.
In that case do the following:

Change the warning message from Your disk is failing
to Back up your data: SMART predicts a larger-than-normal
chance of disk failure.

 When I installed karmic, I too was falsely alarmed by palimpsest's
 warning about a single reallocated bad sector in a disk I've been using
 for years. I ran the manufacturer's test, which said there was no
 problem.
 
 I believe palimpsests's author, as quoted in #7, is not as well as
 informed as he could be about the non-zero number of failures one
 typically sees in disks these days.

[Bug 60325] gedit crashes when 2nd instance opened under another login instance

2006-09-13 Thread gpk
Public bug reported:

Binary package hint: gedit

Distribution: Ubuntu 6.06 (dapper)
Package: gedit
Severity: Normal
Version: GNOME2.14.3 2.14.4
Gnome-Distributor: Ubuntu
Synopsis: gedit crashes when 2nd instance opened under another login instance
Bugzilla-Product: gedit
Bugzilla-Component: general
Bugzilla-Version: 2.14.4
BugBuddy-GnomeVersion: 2.0 (2.14.1)
Description:
Description of the crash:
See below.

Steps to reproduce the crash:
1. Open gedit on main console
2. Connect to computer from another using vnc (vnc server started from xinetd)
3. Log in within VNC session using same user account as logged in on main 
console
4. Attempt to start gedit

Expected Results:
gedit crashes instantly on the original session; gedit fails to start
under the vnc session. The same thing happens if gedit is started first of all 
on the vnc session and an attempt is then made to start it on the main console.

I have not tested to see if this happens if the 2nd login uses a
different user account. However, it does not happen if the vncserver is running 
from within same user login as that under which gedit was run from (i.e. Xvnc 
is started from the user command line via the vncserver script, rather than from
xinetd).

How often does this happen?
Every time the above steps are followed

Additional Information:
None
